• All LEDs light up when someone enters the room but has not yet inserted a magnetic
card. This indicates to the user the location of the card holder.
LED display
• All three LEDs are off when access has been enabled with a guest card and there is a
card in the holder.
• The left LED lights up and the other two are off when access has been enabled with a
staff card and there is a card in the magnetic card holder.
Engineering notes
The magnetic card holder is designed for wall mounting (in flush or cavity-wall mounting
boxes) in conjunction with base-frames and cover-frames from various manufacturers:
− SIEMENS-DELTA futura
− VIMAR idea
− Bticino Classic
− GEWISS Playbus
− AVE Systema 45
Up to four card holders can be connected to the same room bus.
The address is set with 2 DIL switches on the back of the unit (see below).
The maximum permitted current associated with the supply voltage from the HRC3..
room controller must not be exceeded.
(For further information, see data sheets N6313, N6314.)
Mounting
• The HMH3.1/A or HML3.1/A magnetic card holder should be mounted in the
entrance area or lobby of the hotel room at the same height as the light switch.
• First press the card holder into the base-frame and then attach the adhesive label to
the front plate. If the front-plate label is fitted first, it is then difficult to press the card
holder into the base-frame. To remove the unit, it must be unscrewed from the wall
together with the base frame.
• Ensure that there is enough spare cable in the mounting box to allow operation of
the address switches on the PCB.
• The device is designed for fixed installation in a dry, enclosed space.
• For installation in a 4-module mounting box, depth 50 mm.
• Mount horizontally only, with the front plate vertical.
• Do not install AC 230 V devices in the same mounting box.
• Commissioning must be carried out by trained personnel only.
• Do not open the unit.
• Observe all local safety and installation regulations.
